Let's say there are two "deparments" in a florist store.
Department of Local Orders (DLO)
Department of Wire Ins (DWI, no pun intended)
Department of Wire Ins (DWI, no pun intended)
Here's the sales of each deparment in May.
DLO: $10,000 in sales, 100 orders ($100/order)
DWI: $10,000 in sales, 200 orders ($50/order)
COGS was $3,000 each, so...DWI: $10,000 in sales, 200 orders ($50/order)
DLO: $7,000 in sales-COGS
DWI: $7,000 in sales-COGS
DWI had to pay WS commissions and fees ($2,700 + $300), so now it comes down to...DWI: $7,000 in sales-COGS
DLO: $7,000
DWI: $4,000
to pay for all other expenses....DWI: $4,000
Expenses are:
Operating expenses (rent, utilities, etc): $5,000
Salaries: $3,000
Salaries: $3,000
Right, this store made money, $11,000 margin - $8,000 expenses = $3,000!
Let me be clear on this first... If there was no DWI, this store would have lost $1,000. So DWI did indeed contribute to the bottom line of this store. This is obvious even without invoking Contribution Margin for each deparment.
However, I think Contribution Margin analyses should look into deeper than that. Let's start with partitioning expenses. First, easy one, Operating expenses. Let's split into two, so that
DLO "pays" $2,500 for operating expenses
DWI "pays" $2,500 for the same
DWI "pays" $2,500 for the same
Now how much is left in each deparment so far...
DLO: $7,000-$2,500 = $4,500 still left
DWI: $4,000-$2,500 = $1,500 still left
DWI: $4,000-$2,500 = $1,500 still left
Let's split the Salaries; each deparment pays $1,500 each. After all that, here's what's left...
DLO: $4,500-$1,500 = $3,000
DWI: $1,500-$1,500 = $0
DWI: $1,500-$1,500 = $0
So even the dreadful DWI broke even... or did it?
Let's recall that DLO made 100 orders, while DWI took care of 200 orders. Isn't it more reasonable to partition the Salaries into 1:2? In that case, the actual profit "Contribution" would be...
DLO: $4,500-$1,000 = $3,500
DWI: $1,500-$2,000 = - $500
DWI: $1,500-$2,000 = - $500
Right, if we partition the Salary this way, DWI actually lost the money. DWI is break-even in one analysis, while losing money badly in another analysis. I can make DWI even more profitable on paper, if you want... just kidding.
